Title: JPanelGeodesic

Description: Geodesic drawing interface. Drawing the Geodesic curve on the surfaces.

This file also includes the interface for cutting the mesh along the geodesic curve. The mesh can be cut along an open curve (which replaces the original mesh in the scene graph) or the mesh can be cut along a closed curve (which replaces the original mesh with two or more new meshes in the scene graph.

The user may display the geodesic in one of three ways: (1) the smoothed geodesic curve, which is based on a re-triangulation of the surface along Dijkstra's path and a smoothed version of Dijkstra's path. (2) Dijkstra's path along the original mesh vertices and triangle edges. (3) The straight-line distance between points -- Euclidian distance. Of the three display modes the Euclidian path is the only path *NOT* constrained to lie on the surface of the triangle mesh.

Distances for all three path types, for the total path lengths and the most recent point-pairs are displayed in the interface as well.
